油菜套播模式是利用双季稻区冬闲田的有效手段,共生期与播量是影响套播油菜产量的关键因素。为探讨其对套播油菜产量的影响规律,设计共生期及播量裂区试验,调查油菜生长及产量形成。结果表明,共生期及播量均影响着油菜各生育期的生长发育状况,延长共生时间可增加叶面积指数,但易线苗、油菜叶面积指数等
Rape intercropping mode is an effective method to utilize winter fallow field in double cropping rice area. Symbiotic period and sowing rate are the key factors affecting the yield of rapeseed. In order to explore its influence on the yield of intercropped rape, the symbiotic period and sowing interval were designed to investigate the rape growth and yield formation. The results showed that both the symbiotic period and sowing rate affected the growth and development status of rape at each growth stage, and prolonged the symbiotic time to increase the leaf area index, but the leaf area index
